ladies and gentlemen I'm looking at 2006 ml350 and this is also true for all of
the other years going all the way up to $MONTH 2015 the break we're visit
workshop alert is on that basically means i'm driving so keep an eye on the
road that basically means that your pad your brake pads too low in the front
could be the rear and if i reset it and press the brakes again it comes right
back on
also you may see this come on at startup when you put the key in the ignition and
start the engine so we're going to take a look and see what's going on
usually when that brake sensor visit workshop comes on it means that the
brake sensor is now damaged as well it's made to make contact when the brake pads
are very low and it's a plastic piece in between two metal pieces this is what
the new piece looks like and this distance apart that senses the lowness
in the pad this is the electrical connection part so we're going to be
taking a look we're going to replace the pad or the pads that are low and we're
going to also see if we need to replace this piece
so I took off both fronts of the vehicle and checked those pads and they were
fine sensor is fine so I came back and checked the rear and if you take a close
look here you'll see that the pads pretty low to non-existent back here so
these pads are end-of-life on the right side of the vehicle is the we're pad
sensor right here i'm going to be replacing this guy as well as the brake
pad
alright so i'm going to be taking off the brake caliper and i'm going to be
using a tira socket and if you look at my other videos where I have done the
same car before is a tap right here that protects those sockets to them one below
region and take it off and then I'm going to loosen up this caliper
push this bolt out caliper pin that's the first one is a second one that's
down below where the socket won't reach because of the chassis of the car
this will fit so we're going to use this guy this guy can fit in here and second
one down now I'm gonna take off this retaining clip is retaining clip is used
to keep the system cover in place i'll show you how to do that right now using
a screwdriver pop that off and put that into your place now to get the caliper
cover off
I like to just hit a little bit like that that loosens it up we're looking at
the break we're center right here plugs into this electronic interface also
plugs into the brake pad right here and we're going to start by unplugging it
from the interface this is already used damaged gone at the westin to light came
on
typically you want to change it change your brake pads before that happens when
you unplug this the electronics is in here and it's basically a metal detector
right here like this that conducts electricity into
and closes the circuit causing the brake center visit repair shop message to come
on
so we're going to describe this and put on a new one after we put on the brake
pads so now that everything is loosened up we're going to now take this guy off
slide it out of the wall coffee that's the order then the one on the caliper
itself you just take that out there working back and forth
well this one has the three-prong interface its back inside there to hear
the new pads just not right here on the inner side one is where the new sensors
going to plug into back into the interface of the probable just like we
took it up a notch and for just nothing like that the outer pellicer just slide
right in
then once that's done
stick your time going to be a little take it and just slide back into
position just like this it should be no fighting with it then I like to put this
back on
for Bolton thing up and that goes just like before
pistons screws that we took out these right here we're going to make sure that
they go over it back in
we're gonna take a little bit we will put on the sensor next we're going to
use this to just like before taking the lower 11 steps in place then take the
caps and we put them back into the rules that keep the salt and water rain
here's a new sensor start by plugging in and start off by putting this guy on and
you don't force it and just press it in to go in nicely once that's in place you
then take the sensor you press it into position and push this over the way
we've tightened everything up put on the retaining brace put on your sensor along
with the new pads of course and the only thing left to do at this point is to put
back on the wheel so this brake job is done you will do the same thing for the
opposite side of the vehicle course there is no brake sensor we're sense on
that side
this is on the right side of the vehicle only once again thanks for watching
